The bitter taste of tonic water comes from natural base, quinine. Common medicinal antacides (used to relieve heartburn) and bitter tasting Milk of Magnesia, a common laxative, (a suspension of about 8percent of magnesium hydroxide) are also bases. Other bases used around the house are cleaning agents, such as ammonia, and products used to unclog drains, such as Draino. The most important of the strong bases is sodium hydroxide, a solid whose aqueous solutions are used in the manufacture of glass and soap. Water solutions of bases are called alkaline solutions or basic solutions. Substances used to determine whether a solution is acidic or basic are known as indicators. Indicators are organic compounds that change color in a specific way, depending on the acidic or basic nature of the solution. A wide variety of indicators are commonly used in the chemistry laboratory, to identify the acidic or basic nature of an aqueous solution. This experiment uses only two types of indicators: litmus, a vegetable dye, and phenolphthalein. In summary, some of the characteristic properties commonly associated with acids and bases in aqueous solutions are the following: BASES ACIDS Sour taste Bitter taste Change the color of litmus to red Change color of litmus to blue Do not change...
